摘要
紫苏油富含不饱和脂肪酸,具有很高的营养保健作用,但易氧化不耐贮藏。以紫苏油酸值和过氧化值为指标,研究温度、光照、空气和水分含量对紫苏油贮藏稳定性的影响。结果表明:高温、光照、空气和高水分均可促进紫苏油氧化,在贮藏中控制紫苏油水分含量0.10%以下,在25℃以下的低温、干燥、避光的环境中密封贮藏。
Perilla seed oil is rich in unsaturated fatty acids and has high nutrition and health function, but it is easy to oxidation. The acid value and peroxide value were determined during storage to research the effects of temperature,light, air and moisture content on the storage stability of perilla seed oil. The results showed that high temperature,light, air and high moisture content could promote oxidation of perilla seed oil. In the process of storage, some measures, such as controlling perilla seed oil moisture content below 0.10%, choosing temperature below 25 ℃, avoiding light, and sealed storage should he used.
